Prior to purchasing the the Lelit Elizabeth V3, I was really struggling getting another popular espresso machine to dial in and remain consistent from shot to shot. Since getting familiar with the Elizabeth and learning how it works, it's 1) very straightforward, and 2) very consistent from shot to shot. Now most of the variables with grind and puck prep are really what cause any significant changes to the shot. I have made some adjustments in the advanced settings so that I can make sure to see the real-temp (as opposed to just the set temp), etc. Cliff & Pebble were awesome from the start with the purchase and customer service has been excellent. Very happy with my purchase!
